Why would roses that seemed healthy all winter suddenly
dieback as spring arrives? One (Marco Polo) I had pruned
recently and it seemed fine, but now 2 out 3 canes seem
dead and the other doesn’t seem particularly healthy
looking. The other was Paul Neyron, and it seems to have
died back to the ground just recently as well (I plant my
bud union 1 - 2" below the surface, so I have some hope of
recovery). Could it be because it’s been overwet here for
a while? Temperatures have been quite mild for most of
this month.
